在Android中搜索自定义列表视图

Question

我有一个listview，其中包含一个自定义适配器，它有两个TextView和一个图像。我正在使用ActionBarSherlock，并希望添加搜索功能，以便用户可以使用操作栏中的操作搜索两个TextView中的任何一个。问题是，我完全不知道如何做到这一点，因为我是初学者。

这是显示列表视图的类：

public class ItemId extends SherlockListActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Context ctx = getApplication();
        Resources res = ctx.getResources();

        String[] options = res.getStringArray(R.array.item_ids);
        String[] ids = res.getStringArray(R.array.item_names);
        TypedArray icons = res.obtainTypedArray(R.array.item_images);

        setListAdapter(new ItemIDAdapter(ctx, R.layout.idslistitem, ids, options, icons));
        }

这是listview的适配器类：

public class ItemIDAdapter extends ArrayAdapter<String> {

    private LayoutInflater mInflater;

    private String[] mStrings;
    private String[] mIds;
    private TypedArray mIcons;   
    private int mViewResourceId;

    public ItemIDAdapter(Context ctx, int viewResourceId,
            String[] strings, String[] ids, TypedArray icons) {
        super(ctx, viewResourceId, strings);

        mInflater = (LayoutInflater)ctx.getSystemService(
                Context.LAYOUT_INFLATER_SERVICE);

        mStrings = strings;
        mIds = ids;
        mIcons = icons;

        mViewResourceId = viewResourceId;
    }

    @Override
    public int getCount() {
        return mStrings.length;
    }

    @Override
    public String getItem(int position) {
        return mStrings[position];
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        convertView = mInflater.inflate(mViewResourceId, null);

        ImageView iv = (ImageView)convertView.findViewById(R.id.option_icon);
        iv.setImageDrawable(mIcons.getDrawable(position));

        TextView tv = (TextView)convertView.findViewById(R.id.option_text);
        tv.setText(mStrings[position]);

        TextView tv1 = (TextView)convertView.findViewById(R.id.itemids);
        tv1.setText(mIds[position]);

        return convertView;
    }

}
    }
